1) No bashing of other users. If you are seen doing this you will be removed from the community. 2) Try not to advertise communities. If you do, at least make the post respondable so it isn't just taking up space. 3) No "add me" posts. 4) While music recommendations are fine, asking for actual music isn't. Check out communities like ituned and uploads for things of that nature. 5) Insanely large pictures should be behind a cut. 6) Membership is moderated. Empty journals and non-active community journals will not be added.
